HARVESTER-REEL.

SPECIFICATION forming part of Letters Patent No. 685,004, dated October22, 1901i Application filed April 3, 1899. Serial No. 711,473. (Nomodel.)

To all whom it may concern:

Beit known that I, GUsrAvUs A. PADDocK, a citizen of the United States,residing at Beaverdam, in the county of Dodge and State of Wisconsin,have invented certain new and useful Improvements in Harvester-Reels, ofwhich the following is a specication.

The object of my invention is to provide a neat, smoothlyrunning, anddurable reel wherein the beaters shall move swiftly when rst enteringthe grain and slowly when leaving it. This object is gained by theconstruction illustrated in the accompanying drawings, in which Figure lis a view of the reel as seen when standing at the grain end of thesickle-bar; Fig. 2, a sectional view of the reel and itssupporting-standard and driving mechanism as seen from the front, andFig. 3 is a View of the inner ends of the reel-arms and connections inan upright position and of the guide lying horizontally and embracing asection of the flange of the cam-plate. Fig. 4t is an end view of theinner ends of the reel-arms with their connections and an outside viewof the guide in an upright position with a section of the iiange of thecam-plate.

L is a standard for supporting the reel and is hinged by the gudgeon Mto the frame of the machine, its relative position being shown by theguard N. Vertically movable on this is the sleeve-frame I-I, said framebeing provided at its upper part with a bearing for the verticaldrive-shaft K. To the opposite end of the sleeve-frame is secured acircular cam-V plate G, with an annular ange g. In the front part of thesleeve-frame and also in the cam-plate are bearings for the reel-shaftA, to one end of which is secured the bevel gear- Wheel I. Thebevel-pinion J, which meshes With said gear-wheel, rests in the bearingsin the sleeve-frame and with it is vertically movable on the drive-shaftK and is supplied with a key which its into and slides in a groove insaid shaft, which, like the standard L, is hinged to the harvester-frameat its lower part. The means of holding the standard L and sleeve-frameIl in position are common in the art, and therefore do not need to beshown here.

The reel-head has four radial arms b cornl ing out at right angles tothereel-shaft A next i tothe cam-plate, and four others, b', standing at anangle at the other end, the outer ends of these furnishing bearings inwhich pivots formed of the rodscoscillate. Triangularbearing-platesformed of castings E rest upon the rods c. The lugs t', i', and h, arefitted to the rods, and the reel arms are secured outside the castings.The bolts e pass through the inner ends of both the short armsD,thelongarmsD, and the castings.' The eyebolts e encircle the rods and passthrough the castings and long arms. The bolts e pass through the rods c,castings E, and short arms D. The castings are supplied at their innerends with bearings d, and fitted to these are the guides F, said guidesbeing provided with cam grooves which iit the flange of the cam-plate G.Small blocks f are bolted tothe outer portion of these guides, thebolt-holes therein being so made that they can beadjusted to take upwear. These blocks also secure the guides to the above-mentioned fiangewhen the reel. is taken apart, thus preventing danger of their loss. Inthese views the reel-head and cam-plate G are, for convenience, shownproportionately larger than I prefer to make them for use. Also thefront of the cam-plate is shown somewhat higher. l

It will readily be seen that the beater D (shown above the cam-plate inFig. l) will move about three times as fast in the irst quarter of arevolution made by the reel as the one next before it. The reel-shaftshould revolve about thirtythree per cent. faster than for an ordinaryreel, as by tilting it back the practical working speed of the reel willstill be less than in other reels, while by tilting it ahead itspractical working speed can be doubled. At the same time the beatersalways leave the grain slower than in other reels.

It will be seen that when the eccentric is raised or lowered therelative positions of its front and rear sides are not changed, or, inother words, it is movable verticallywithout tilt.

I do not claim, broadly, the reelarms pivoted yto radial arms on areel-shaft and guided throughout their revolution by a carnplate with aflange, as a patent has already been granted to me on a reel embracingthe said construction, wherein the change of lOO movement was gained byusing an irregularlycurved cam-plate With a cam-groove and guidesconsisting of rollers running therein, the cam-plate not being movableto front and rear. The present construction has the followingadvantages: The reel-arms have a steady even movement, given by thecircular flange. As will be seen, so long as the guides are moving fromthe reel-shaft the outer ends of the reel-arms have an acceleratedmovement which gradually changes to a slow movement as the guides beginto move back toward the reel-shaft. This gradual change of mot-ion canbe fully attained only by the cam-plate being a circular eccentric. Thenthe practical inc rease of the Working speed of the reel can only beeffected by tilting the front of the eccentric downward, and by mountingsaid eccentric on an upright standard Which can be tilted to front andrear the operator in moving the reel ahead is enabled to also increaseits practical Working speed by the same movement. The bearings of theguides are also held much more firmly in place by securing thelndirectly to the pivotal bearings of the radial arms, and, lastly, byhaving the guides held in position by a single flange of the eccentric agreater variation of speed can be obtained and a smaller eccentric canbe used, thus making the reel lighter, cheaper to build, and moreeffective.

I claim as my inventionl. In a harvestingmachine, an upright standardhinged at its lower part to the frame of the machine, a sleeve -framevertically movable thereon, an eccentric with a (iange secured to saidsleeve-frame, a reel-shaft passing through said eccentric at a pointdistant from its center and having bearing in the sleeve-frame, radialarms secured to said reel-shaft, bearing-plates and reel-arms rigidlysecured together and pivoted to the radial arms, beaters rigidly securedto the outer ends of said reel-arms, and guides pivoted to the innerends of said bearing-plates, said guides being secured in movableengagement with said eccentric.
